Actually its not too bad my large one passes a very noticeable small dog turd sized dropping a few days after a good meal. I just net it out. When i was moving apartments he lived in a rubbermaid tub for awhile and i only offered him token meals about every ten days, usually just a single shrimp. After about two weeks i never saw any solid waste during a water change, even after a few meals nothing of notice came out. After a few good meals though he started right back up on his four day routine.
I will be honest sometimes i overlook his water changes for two weeks (and occasionally more) with no ill effects. But that kinda water change routine should put size on him rapidly. But i suppose thats relative with big water changes and all the food he can eat mine only grows about 1/4 inch a month on a good month. Probably faster length gain at smaller sizes since the fish isnt putting on so much body mass.
